Agaba Derrick - Uganda

Agaba Derrick uses science to save lives. “If the refugees can't have clean water then life will not be good for them,” he says.

He’s a volunteer lab assistant with Uganda Red Cross and he tests the chlorine and aluminium sulphate content of water before it’s shipped to a refugee camp in Uganda’s north.

“This lab work is the most important part of the process. We need to make sure the water is fit for human consumption. I always had a passion to help people, and that's what we're doing here.” Photo: Tommy Trenchard/Panos/IFRC
